Having recently shown that high-order unstructured discontinuous
Galerkin (DG) methods are a discretization method for systems of
hyperbolic conservation laws that is well-matched to execution on GPUs,
in this talk I will explore both core and supporting components of
high-order DG solvers for their suitability for and performance on
modern, massively parallel architectures. Components examined range from
software components facilitating implementation to strategies for
automated tuning and, time permitting, numerical tweaks to the method
itself. In concluding, I will present a selection of further design
considerations and performance data.
